摘要
针对传统光谱采集设备体积大,成本高的缺点,基于HAMAMATSU公司开发的MEMS-FPI型光谱传感器C14272,设计了以FPGA作为主控的红外光谱传感器驱动采集电路。电路包括可调谐滤波器的电压驱动模块、光谱与温度的信号采集模块、USB传输模块等。实验证明,该电路采集的C+L波段ASE光源的光谱与仿真所得光谱相近,实现了对光谱传感器的驱动以及光谱数据的采集。电路可以探测的波长范围为1 350~1 650 nm,全波段光谱分辨率小于18 nm。电路整体设计结构紧凑,成本低,在物质成分定性检测等特定领域有一定应用价值。
Aiming at the disadvantages of large volume and high cost of traditional spectrum acquisition equipment, a driving and acquisition circuit of infrared spectrum sensor controlled by FPGA is designed based on MEMS-FPI spectrum sensor C14272 developed by HAMAMATSU. The circuit includes voltage driving module of the tunable filter, spectrum and temperature signal acquisition module, USB transmission module and so on. The test results show that the spectrum of the C+L band ASE light source obtained by the circuit is similar to the simulation spectrum, which realizes the driving of the spectrum sensor and the collection of spectrum data. The wavelength detection range of the circuit is 1 350~1 650 nm and the full band spectral resolution is less than 18 nm. The design is compact in structure and low in cost, which is helpful in specific fields such as qualitative detection of material composition.
